Introduction
Whether a myopic patient needs to wear glasses when using a smartphone depends on individual circumstances. It is normal for myopic individuals to see nearby objects clearly; however, distant objects appear blurry, leading to reduced visual acuity and difficulty reading. Since smartphones require close-up, detailed viewing, if the patient uses the device for no more than 30 minutes at a time and accumulates no more than 2 hours of total daily usage, corrective lenses may not be necessary.
Myopia simply means difficulty seeing distant objects clearly; when viewing objects, the eyes easily become fatigued. The primary manifestations of myopia are reduced distance vision and visual fatigue. Although higher degrees of myopia generally correlate with poorer distance vision, there is no strict proportional relationship. Myopia can be categorized as either congenital or acquired. So why can individuals with myopia see their mobile phones clearly without wearing glasses?
Why Individuals with Myopia Can See Mobile Phones Without Glasses
Whether a person with myopia needs to wear glasses while using a mobile phone depends on individual circumstances. It is normal for myopic individuals to see nearby objects clearly—distance vision, however, is impaired, resulting in blurred vision when reading or viewing distant objects. A mobile phone is a device requiring close-up, detailed visual attention. If usage duration is limited to no more than 30 minutes per session and total daily usage does not exceed two hours, the eyes may remain relatively relaxed, allowing comfortable use of the phone without glasses. However, if one spends excessive time on the phone daily—or has high myopia—using the phone without glasses may cause noticeable eye strain, necessitating corrective lenses.
Individuals with myopia should consider wearing glasses while using mobile phones. Additionally, it is advisable to avoid prolonged mobile phone use, as this can significantly exacerbate symptoms of eye fatigue. For those with myopia, wearing corrective lenses during phone use can effectively alleviate ocular discomfort caused by screen light exposure.
In daily life, patients should maintain a positive mindset, actively cooperate with physicians during treatment, take prescribed medications as directed (in terms of both dosage and timing), and pay attention to routine eye care—thereby facilitating prompt improvement in their condition. We hope this response has been helpful.
